arm64: dts: st: set RIFSC as an access controller on stm32mp21x platforms

Browse Source 
Similarly to stm32mp23x/25x platforms, the RIFSC is a firewall
controller. Declare it as an access controller, keep the "simple-bus"
compatible in case CONFIG_STM32_FIREWALL is not set and update the
child nodes.
